Description

Technical Field

[0001] This utility model relates to the field of industrial grinding and dust removal technology, and in particular to a comprehensive dust control device for grinding stations in foundry workshops. Background Technology

[0002] During the grinding of castings in a foundry, a large amount of dust and metal shavings are generated. These pollutants not only seriously pollute the workshop environment but also endanger the health of the operators. Long-term exposure to dust can easily lead to occupational diseases such as pneumoconiosis, and dust can also pose safety hazards such as explosions.

[0003] Most existing dust control equipment is single-function, only capable of treating one type of dust or metal shavings, and cannot achieve synergistic treatment of both. In the grinding station of a foundry, dust and metal shavings often coexist, requiring operators to use multiple devices simultaneously. This not only increases equipment investment and floor space requirements but also complicates operation and maintenance. Moreover, these devices consume a lot of energy during operation, which is inconsistent with the current trend of energy conservation and environmental protection.

[0004] Meanwhile, existing dust control equipment suffers from numerous structural design flaws. For example, some equipment has fixed dust hood positions, making it impossible to flexibly adjust according to the specific grinding operations, resulting in poor dust collection efficiency; the installation and disassembly of dust collection boxes are inconvenient, requiring significant time and manpower to clean the internal dust and debris; and the filter bag replacement process is cumbersome, affecting the continuous operation of the equipment. These problems severely restrict the effectiveness and efficiency of dust control in foundry workshops, failing to meet the demands of modern production. Therefore, developing a device that can efficiently, conveniently, and energy-efficiently control dust and metal debris at grinding stations in foundry workshops is of significant practical importance.

[0005] The above background information is provided only to aid in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Utility Model Content

[0006] The purpose of this utility model is to propose a comprehensive dust control device for the grinding station in a foundry workshop, so as to solve the technical problems existing in the prior art.

[0007] Therefore, the present invention adopts the following technical solution:

[0008] A comprehensive dust control device for a grinding station in a foundry includes a dust collection frame, an electrostatic adsorption unit, a negative pressure collection unit, a dust collection box, and a grinding platform. The dust collection frame is fixed to one side of the grinding platform. The electrostatic adsorption unit is connected to the vertical side of the dust collection frame facing the grinding work area. The negative pressure collection unit is assembled on the top of the dust collection frame. The dust collection box is located below the grinding platform and connected to the dust collection frame. The electrostatic adsorption unit is connected to the dust collection box through a guide plate, and the negative pressure collection unit is connected to the dust collection box through a suction motor and an air inlet pipe.

[0009] Furthermore, the negative pressure collection unit includes a dust hood, a suction motor, a corrugated pipe, a universal ball joint, and a telescopic arm; the suction airflow generated by the suction motor collects dust from the dust hood into the dust collection box; the dust hood of the negative pressure collection unit is fixed to the side column of the platform via the universal ball joint and the telescopic arm, the air inlet of the hood is connected to the corrugated pipe through a quick-release clamp with a sealing ring, the other end of the corrugated pipe is connected to the air inlet of the suction motor, and the air outlet of the suction motor is connected to the air inlet pipe of the dust collection box.

[0010] Furthermore, an asbestos sealing gasket is installed at the flange connection between the suction motor and the dust collection box.

[0011] Furthermore, the dust collection hood of the negative pressure collection unit is a horn-shaped dust collection structure, connected to a telescopic arm via a universal ball joint. The telescopic arm is adjustable, includes a locking knob, and is fixed to the side column of the platform. The cantilever bracket can rotate horizontally from 0-180° and tilt vertically from 0-90°, covering the space above the grinding station.

[0012] Furthermore, the electrostatic adsorption unit includes a grid plate, an adsorption plate, a guide plate, and a mounting base. The grid plate of the electrostatic adsorption unit has a hollow mesh structure and is snap-fitted into the dust collection frame. The adsorption plate is tilted and fixed to one side of the grid plate by the mounting base with tilt locking function, and the mounting base can maintain the stability of the tilt angle of the adsorption plate. The end of the adsorption plate is connected to the guide plate, which is a plate-shaped structure with a rounded transition at one end, extending to the air inlet pipe of the dust collection box. The connection between the guide plate and the air inlet of the dust collection box is adapted to the rounded contour to ensure smooth connection.

[0013] Furthermore, the adsorption plate is installed at an angle of 30-45°.

[0014] Furthermore, the guide plate is inclined at a 15-20° angle, with one end receiving the grid plate and the other end connecting to the end of the adsorption plate extending to the dust collection box air inlet pipe. The end of the guide plate near the dust collection box air inlet pipe is arc-shaped, which is adapted to the contour of the dust collection box air inlet pipe. By using the inclined angle and arc transition, the material collected by the adsorption plate is guided smoothly into the dust collection box.

[0015] Furthermore, the dust collection box is connected to the bottom of the dust collection frame below the grinding platform. One side of the dust collection box is equipped with a drawer, which slides through the double-sided linear guide rails to form a drawer-type dust collection and storage structure.

[0016] Furthermore, the drawer has a built-in filter bag with an elastic retaining ring on the top. The retaining ring can be inserted into the corresponding slot on the top of the dust collection box. When the filter bag is to be replaced, the filter bag can be pulled out by pulling the retaining ring.

[0017] Furthermore, a counterweight is provided at the bottom of the filter bag to keep the filter bag vertical under the impact of airflow.

[0018] The beneficial effects of this utility model compared with the prior art include:

[0019] 1. More comprehensive treatment effect: Most existing dust control equipment can only treat dust or metal shavings separately. However, this utility model can effectively adsorb metal shavings and efficiently collect suspended dust by working together with the electrostatic adsorption unit and the negative pressure collection unit. This achieves comprehensive treatment of pollutants in the grinding station of the foundry workshop and greatly improves the air quality of the workshop.

[0020] 2. More Convenient Operation and Maintenance: Replacing filter bags and cleaning dust collection in traditional equipment often requires complex operations and consumes a lot of time. In this invention, the dust collection box adopts a drawer-type structure, which can be easily pulled out for cleaning; the filter bags are connected to the dust collection box by elastic retaining rings, and replacement can be done simply by pulling the retaining rings, making operation simple and quick. At the same time, the position of the dust collection hood of the negative pressure collection unit can be flexibly adjusted to adapt to different grinding operation needs.

[0021] 3. More stable equipment performance: The counterweight at the bottom of the filter bag keeps it vertical under airflow impact, ensuring stable filtration effect; the sealing structure design of each component, such as the asbestos gasket at the connection between the suction motor and the dust collection box flange, effectively prevents dust leakage and ensures stable operation of the equipment. In addition, the equipment has a reasonable structural design, with all components firmly connected and a long service life. Attached Figure Description

When replacing the filter bag 42, pulling the retaining ring allows it to be removed. A counterweight is located at the bottom of the filter bag 42 to keep it vertical under airflow impact.

[0032] The technical principle of this utility model is as follows:

[0033] Electrostatic adsorption principle: When the adsorption plate 32 in the electrostatic adsorption unit 3 is working, it generates an electrostatic field. When metal debris and dust generated at the grinding station in the foundry pass through the electrostatic field, they will be adsorbed onto the adsorption plate 32. Since the adsorption plate 32 is installed at an angle of 30-45°, under the influence of gravity and subsequent dust, the adsorbed metal debris will slide along the guide plate 33 along the adsorption plate 32.

[0034] Negative pressure suction principle: When the suction motor 22 of the negative pressure collection unit 2 is working, it will create a negative pressure at the dust collection hood 21, which will suck in the dust generated by grinding. The dust enters the dust collection box 4 through the corrugated pipe 23, the suction motor 22 and the air inlet pipe. In the dust collection box 4, the dust is filtered by the filter bag 42 and clean air is discharged.

[0035] Synergistic working principle: The electrostatic adsorption unit 3 mainly adsorbs and collects metal shavings and some heavier dust, while the negative pressure collection unit 2 mainly collects dust suspended in the air. The two work together to achieve comprehensive treatment of dust and metal shavings in the grinding station.

[0036] The operation process of this utility model is as follows:

[0037] 1. Equipment installation: Fix the dust collection frame 1 to one side of the grinding platform 5, and install the electrostatic adsorption unit 3, the negative pressure collection unit 2 and the dust collection box 4 respectively, ensuring that all components are firmly connected and well sealed.

[0038] 2. Equipment debugging: Adjust the telescopic arm 25 and universal ball joint 24 of the negative pressure collection unit 2 so that the dust collection hood 21 is aligned with the grinding operation area, and fix the position by locking the knob; adjust the tilt angle of the adsorption plate 32 in the electrostatic adsorption unit 3 so that it is at the optimal adsorption angle of 30-45°.

[0039] 3. Start-up: Turn on the suction motor 22 and the electrostatic adsorption unit 3 to begin the grinding operation. During the operation, the electrostatic adsorption unit 3 adsorbs metal debris and some dust. The metal debris enters the dust collection box 4 through the guide plate 33. The negative pressure collection unit 2 draws the suspended dust into the dust collection box 4 and filters it through the filter bag 42.

[0040] 4. Replacement of filter bag 42: When the filter bag 42 adsorbs too much dust and affects the filtration effect, stop the equipment operation, pull out the dust collection box drawer 41 along the double-sided linear guide pair, pull the elastic retaining ring at the top of the filter bag 42 to pull the filter bag 42 out of the dust collection box 4, replace it with a new filter bag 42 and re-insert it into the slot 43, clean the pollutants inside the dust collection box 4 and then push it back into its original position.
